The Pyrenees, where Euro-Siberian, Mediterranean and alpine faunas join together, have a large biodiversity of bumblebees. We compiled historical literature records of bumblebee species from the Spanish Pyrenees, and then compared these to contemporary surveys to assess trends in elevational distribution. Twenty-eight species (including thirty-five subspecies) were found in the contemporary survey. Nine species and two subspecies previously present were not detected, some included on the Spanish Red List. With the exception of a few species, a reduction of the altitudinal range and an orophilous tendency was observed at both upper and lower elevational levels, suggesting an upward trend towards better-preserved high areas. Our results reinforce the need to develop new protection programs and more restrictive conservation measures for bumblebee populations, species and their habitats.
比利牛斯山脉是欧洲-西伯利亚、地中海和高山动物区系的交汇处，拥有丰富的熊蜂生物多样性。我们收集了西班牙比利牛斯山脉熊蜂物种的历史文献记录，然后将这些记录与当代调查结果进行比较，以评估海拔分布趋势。在当代调查中发现了28个物种（包括35个亚种）。之前存在的9个物种和2个亚种未被发现，其中一些被列入西班牙红色名录。除少数物种外，在海拔上限和下限处均观察到海拔范围缩小和向山性趋势，这表明向保护更好的高海拔地区呈上升趋势。我们的研究结果强化了为熊蜂种群、物种及其栖息地制定新的保护计划和更严格保护措施的必要性。
